Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
Netgear XR300 v1.0.3.78 was discovered to contain a stack overflow via the passphrase parameter at bridge_wireless_main.cgi. This vulnerability allows attackers to cause a Denial of Service (DoS) via a crafted POST request.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis · high confidence

A stack-based buffer overflow vulnerability exists in the Netgear XR300 router firmware v1.0.3.78. The vulnerability is located in the bridge_wireless_main.cgi endpoint, where the passphrase parameter in a POST request does not properly validate input length before copying it to a fixed-size stack buffer. This allows an attacker to overwrite stack memory by sending an oversized payload, causing the device to crash and resulting in a Denial of Service.

MitigationApply the latest Netgear firmware update for the XR300 model when available. As an interim control, restrict access to the device's web management interface to trusted networks or disable remote administration entirely.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.

dbcve checks

Work through these to decide whether this CVE applies to you.

  1. Confirm device model is Netgear XR300
    Access the router web interface and check the device model in the status/dashboard page, or log into the router via SSH and run 'cat /proc/cpuinfo' or check the label on the device
    Affected if The device model is not Netgear XR300
  2. Verify firmware version is exactly 1.0.3.78
    In the router web interface, go to Administration > Firmware Update or Router Status page and check the current firmware version displayed
    Affected if Firmware version is not 1.0.3.78 (the vulnerability affects only this specific version)
  3. Confirm the web management interface is accessible
    Attempt to access the router's web interface at the default gateway IP (typically 192.168.1.1) from a browser. Check if bridge_wireless_main.cgi responds to requests
    Affected if The web interface is unreachable or the bridge_wireless_main.cgi endpoint does not exist or respond
  4. Check if remote administration is enabled
    In the router web interface, go to Advanced > Remote Management and verify if 'Enable Remote Management' or similar option is turned on
    Affected if Remote administration is enabled, making the vulnerable endpoint accessible from external networks

You are affected if you have a Netgear XR300 router running firmware version 1.0.3.78 with its web management interface accessible, especially if remote administration is enabled.
